Five series: chipset and driver separate them
TRK01 is the value range from 25W to 30W at 100-105 lm/W with a 15°, 24° or 36° lens — the standard spot for a retail ceiling where the budget is set by the fit-out contractor. TRK02 moves to a Citizen COB chip at 110-120 lm/W with four beam options from 12° to 60°, which is the range used where the merchandise has to look right under the light.
TRK03 is the premium line: Citizen COB with an Osram flicker-free driver at 120 lm/W, from 25W to 35W, plus 5W and 10W versions on a Luminus chip with a BOKE driver. TRM is a compact cylindrical body from 15W to 35W in a 90-130V or 200-240V version. ZTRK03 is a 10W zoom spot with a 15-55° adjustable beam for accent work.

Sudut Sorot decides the throw
A track light is an accent tool, and the beam angle is the specification that changes the result more than the wattage does. At a 3 m ceiling with a 24° lens, the pool of light on the floor is about 1.3 m across; at 12° it is about 0.6 m. The narrow beams are for highlighting a single product, the wide ones for washing a wall or lighting a walkway.
The distance rule is simple: pool diameter is roughly 2 x distance x tan(angle ÷ 2). A 36° lens at 3 m gives a 1.95 m pool, which is right for a table or a display plinth; a 60° lens at the same height gives 3.4 m, which is a wall wash rather than a spot.
| Sudut Sorot | Pool at 3 m | Pool at 5 m | Typical use |
|---|---|---|---|
| 12° | 0.6 m | 1.1 m | single product, jewellery case |
| 15° | 0.8 m | 1.3 m | accent on a mannequin or a plinth |
| 24° | 1.3 m | 2.1 m | general retail accent |
| 36° | 1.9 m | 3.2 m | table, display group |
| 38° | 2.1 m | 3.4 m | walkway, small area |
| 60° | 3.5 m | 5.8 m | wall wash, wide coverage |
Calculated as 2 x distance x tan(angle/2). Real pools are softer at the edge than the calculation suggests.
Replacing halogen track spots
A track installation is usually relamped from 50W or 75W halogen spots, and the LED equivalent is roughly a tenth of the wattage for the same delivered light. The reason to change is not only the electricity: a halogen spot runs at several hundred degrees at the front, which is a fire and burn risk in a retail display, and it shifts colour as it ages.
| Existing halogen spot | Output | LED replacement | Power saved | Comment |
|---|---|---|---|---|
| 35W halogen spot | about 400 lm | 5-7W | about 82% | small accent, cabinet |
| 50W halogen spot | about 700 lm | 7-10W | about 82% | standard retail accent |
| 75W halogen spot | about 1,100 lm | 12-15W | about 82% | high ceiling retail |
| 100W halogen (AR111) | about 1,500 lm | 20-25W | about 78% | feature wall, lobby |
Halogen output is a typical catalogue value including the dichroic reflector loss.
Chip, driver, flicker and the track system
The chipset is what separates a track light that photographs well from one that does not. Citizen COB is used on TRK02, TRK03 and TRM; Luminus on the low-wattage TRK03 and the zoom. The driver matters as much: Osram and Lifud flicker-free drivers are used on the ranges where the installation is filmed or where staff work under the light for a full shift.
The track adaptor is a separate decision. Standard 2-wire, 3-wire and 4-wire three-phase adaptors are available, and the adaptor has to match the existing track rather than the fixture. Tell us the track brand or send a photo of the adaptor and we match it before shipping — a mismatched adaptor is the most common reason a track order comes back.

A GU10 track head without a lamp is available (LL-TRH01) for projects that supply their own lamps. For ceiling panels in the same shop see the panel range.
Frequently asked questions
What replaces a 50W halogen track spot?
A 7W to 10W LED track light with a 24° beam, giving about 700 lm against the halogen's 700 lm. The pool of light is the same if the beam angle matches; the difference is the heat and the colour shift.
Which beam angle for a retail display?
24° for a general product accent at 3 m, 15° or 12° for a single item, and 60° for a wall wash. If the ceiling is higher than 4 m, move one step narrower rather than increasing the wattage.
Will the track adaptor fit my existing track?
That depends on the track brand. We supply 2-wire, 3-wire and 4-wire three-phase adaptors and match the adaptor to your track if you send the brand or a photo of the existing head.
Are the track lights flicker-free?
TRK03 uses an Osram flicker-free driver and the low-wattage TRK03 uses BOKE; the zoom uses Lifud. For filmed installations confirm the model and we provide the ripple figure.
What CRI for a clothing store?
Ra90. It is the level at which fabric colours and skin tones read correctly under the light, and it is available on request across the range.
Can track lights be used in a hotel lobby?
Yes, and the TRM cylindrical body is the usual choice for a lobby because it reads as a designed fixture rather than a utility spot. For plastered ceilings with no track, use the gimbal downlight range.
